I thought you were super tall because the bar was mounted really high. Then I checked again, realized the squat rack itself isn't as tall as I thought it was. I thought you were like 6'5" from the rack and wondered how long it took you to get to 275 from your height!

There are two primary reasons why curling in the squat rack reaches a high level of Douchebaggery...

1) You are using a piece of equipment you don't need to and are preventing someone who actually HAS to use that piece of equipment to perform their excercise.

And the biggest reason...

2) Any normal person that has done any weightlifting at all can around deadlift 200-300 lbs MINIMUM. If you are so fucking lazy or weak that you can't lift 75 or 95 or whatever you are curling off the floor then you need to just kill yourself...
